Question

A pendulum bob of mass 50 g is suspended from the ceiling of an elevator. The tension in the string if the elevator goes up with uniform velocity is approximately, 0 . 30 N, 0 . 40 N, 0 . 42 N, 0 . 50 N

MARKS App · Accepted Answer

As elevator goes up with uniform velocity then acceleration a = 0 T = m g + a T = m g = 5 × 10 - 3 × 10 = 0.5 N
